DOOR FOR HOPPER-BOTTOM CARS.

SPECIFICATION forming part of Letters Patent No. 670,615, dated March26, 1901.

Application filed January 28, 1901. Serial No. 44,428. (No model.)

To all whom it may concern:

Be it known that I, GEORGE I. KING., a citizen of the United States,residing at the city AIO of Detroit, in the county of Wayne, State ofMichigan, have invented a certain new and useful Improvement in Doorsfor Hopper- Bottom Cars, of which the following is a full, clear, andexact description, such as will enable others skilled in the art towhich itappertains to make and use the same, reference being had to theaccompanying drawings, forming part of this specification, in which-Figure 1 is a side elevational view of a portion of a hopper-bottom carupon which is mounted my improved door. Fig. 2 is a vertical sectionalview on line 2 2, Fig. l; and Fig. 3 is an inverted plan View of aportion of the door and its hanger.

This invention relates to a new and useful improvement in doors designedespecially for use in connection With hopper-bottom y cars-such, forinstance, as is shown and described in United States Patent No. 658,783,dated October 2, 1900.

The object .of this present invention is to simplify the construction ofdoors for such a type of cars, the door being strong and well able towithstand the rough usage to which it is subjected.

. With this object in View the invention consists in the construction,arrangement, and combination of the several parts, all as willhereinafter be described and afterward pointed out in the claims.

In the drawings, l indicates the side sill of the car; 2, the sidesheet; 3, the angles reinforcing the side sheet; 4 the hopper-slieet,and5 the strengthening-plate riveted to the side sillv and hopper-sheet andreinforcing the latter, all of the above parts being shown in my formerpatent above referred to.

6 indicates the door as an entirety, which door is disposedhorizontally, said door closing the exit for the load, of which the sidehopper-sheet forms one` wall. This door in practice extends transverselythe car and cooperates with a companion, (not shown,) which companion issimilar in all respects and is operated in like manner, though in anopposite direction. Door 6 is composed of a sheet of metal 7, formingthe panel of the door, said sheet being supported bylongitudinally-arranged angles 8 and 9, respectively, andtransversely-arranged angles 10 at the side edges of the door. cast orrolled, in which latter event the vertical members or legs may besheared to taper the angles at their ends.

12 indicates a plate having an inturned iiange 13 at its lower edge,which inturned iiange fits under the horizontal leg of the angle l0,said flange being riveted to said angle and to the outer edge of thepanel-sheet 7, as shown. There is a plate 12 at each side of the door,said plates serving as hangers. Plates 12 carry a casting 12a at theirupper ends, which casting forms a pi vot-eye for c0- operating with thepivot-lug 14, secured to the strengthening-plate 5. The pivot-lug 14.-is preferably reinforced by suitable webs, whereby it serves as abracket-brace for the strengthening plate and the side hoppersheet. Thehanger-plates 12 being pivoted, as shown, permit the door to be openedoutwardly on an arc of a circle described from the pivot-point of thebracket 14, so that when the door is in its open position it is slightlytilted or canted to enable any particles lodging thereon to readily bedischarged.

The mechanism operating the door preferably consists of a link 15,pivotally connected to lug-castings mounted on the angle 9, said linkbeing pivotally mounted on a rock-arm 16, extending from the inner endof a shaft 17. This shaft carries a ratchet- Wheel 18 on its outer end,with which coperate pawls 19. A stop 20, preferably secured to thecenter sills of the car, arrests the rock-arm in its inward movementwhen the pivotal points of the link are past a line of dead-center,which construction serves to lock the door in its closed position, theratchet-pawls serving to prevent the rock-arm from being dislodged.

When it is desired to open the door, the

pawls are disengaged from the ratchet and the rock-arm turned down,which, through These angles may be,

the link connections of the door, causes the n rangement, construction,and combination of.

IOO

the several parts of my device may be made and substitdted for thoseherein shown and described without in the least departing from thenature and prineiple of my invention.

Having thus described my invention, What I claim, and desire to secureby Letters Patent, is-

1. In combination with a hopper-bottom ear, a door for opening andclosing the exit for the load, said door comprising a panel, angles 8, 9and 10, and plate-hangers pivoted at their upper ends, the lower edgesof said plate-hangers being anged under the horizontal legs of angles 10substantially as described.

2. In Combination with a hopper-bottom oar, a door for opening andClosing the exit of the load, said door comprising a panel-sheet 7,

longitndinally-disposed angles S and 9 arranged at the inner and outeredges; thereof, angles 10 arranged at the side edges of the door,plate-hangers 12 Hanged under the horizontal legs of the angles 10 andriveted thereto, and castings riveted to the upper ends of theplate-hangers for pivotally mounting` said hangers and their supporteddoor upon the ear; substantially as described.

In testimony whereof I hereunto aiiix my signature, in the presence oftwo Witnesses, this 21st day of January, 1901.

GEORGE I. KING.
